Definitions

  • the present invention relates to a system and a method for creating a three-dimensional model of the teeth and bite by scanning and aligning dental impressions.
  • the present invention is related to the field of manufacturing of dental restorations such as crowns, bridges, abutments and implants.
  • dental restorations such as crowns, bridges, abutments and implants.
  • the dentist will prepare the teeth e.g. a damaged tooth is grinded down to make a preparation where the crown is glued onto.
  • An alternative treatment is to insert implants (titanium screws) into the jaw of the patient and mount crowns or bridges on the implants. After preparing the teeth or inserting an implant the dentist normally makes an impression of the upper jaw, the lower jaw and a bite registration or a single impression in a double-sided tray (also known as triple trays).
  • the impressions are sent to the dental technicians who actually manufacture the restorations e.g. the bridge.
  • the first step to manufacture the restoration is traditionally to cast the upper and lower dental models from impressions of the upper and the lower jaw, respectively.
  • Figure 1a and figure 8 shows a dental model and a impression, respectively.
  • the models are usually made of gypsum and often aligned in a dental articulator using the bite registration.
  • the articulator simulates the real bite and chewing motion.
  • the dental technician builds up the dental restoration inside the articulator to ensure a nice visual appearance and bite functionality. A proper alignmentof the cast in the articulator is crucial for the final restoration.
  • the first step in the CAD manufacturing process is to create a 3-dimensional model of the patient's teeth. This is traditionally done by 3D scanning one or both of the dental gypsum models. The 3-dimensional replicas of the teeth are imported into a CAD program, where the entire dental restoration or a bridge substructure is designed. The final restoration 3D design is then manufactured e.g. using a milling machine, 3D printer, rapid prototyping manufacturing or other manufacturing equipment. Accuracy requirements for the dental restorations are very high otherwise the dental restoration will not be visual appealing, fit onto the teeth, could cause pain or cause infections.
  • impression scanners An alternative to impression scanners is direct in-the-mouth scanners.
  • impression scans have a clear number of advantages compared to in-the-mouth scanners including no mandatory equipment investment at dentist clinic, virtually no training for impression taking, shorter chair time, a physical model can always be poured in case of scanning problems or used as physical reference, low accuracy for in the mouth scanners, no powdering of the patient mouth necessary, and significantly reduced difficulties in capturing the antagonist and larger areas and contrary to in-the-mouth scan the impression has the margin line clearly visible.
  • US 2004/0133293A1 discloses methods and systems for treating teeth include capturing a digital dental model taken within an oral cavity, modifying the digital model in planning a dental treatment or in designing a dental prosthetic, and creating a physical model from the original or modified digital models.
  • the invention relates to a method of manufacturing a dental model from an obtained three-dimensional model as defined in claim 1.
  • Such a method of manufacturing dental models from a obtained data may enable easier storage of dental models in that only the data is stores and a physical model may be produced if needed.
  • Such models may also be utilized to omit the necessity to ship impressions and/or models between sites such as place of manufacturing abutments and a place of handling models and/or scanning.
  • Dental impression a negative impression of the teeth preferably made in a tray.
  • Dental model a positive replica of the teeth made from the dental impression.
  • An improved scanning and alignment method for scanning dental impressions used as input for CAD manufacturing of dental restorations is described avoiding the costly and time consuming manufacturing of dental gypsum models. Impression scanning will also improve quality since the traditional casting process and dental model segmentation introduces errors. Furthermore, impression scanning will not increase chair time for patients at the dentist, there is no mandatory entry cost for the dentist, no education of the dentist is required and the overall manufacturing time is reduced thereby improving patient satisfaction and potentially avoiding temporary restorations.
  • the scanning of dental impressions by optical 3D scanners is very challenging mostly due to a lack of visibility in cavities.
  • a traditional 3D scan will thus result in a lack of coverage, i.e. the 3D scan may have holes or missing areas that have not been scanned.
  • a solution to that problem is disclosed.
  • the present invention provides a solution to that problem. As described above, one solution may be to rescan, optionally using a different scanner and/or a different scanner setting, one or more regions of interest of the impression, to provide a scan having a better quality, such as fewer holes, or no holes in the region of interest.
  • the term scan "quality" means quality in relation to coverage and accuracy of the scan. Insufficient coverage might be automatically detected by triangulation of the surface and then locating the holes on the surface. A good quality requires no holes or only very few holes in the regions of interest. If any holes are accepted, the position of such holes may not interfere with the production of an accurate three-dimensional model. In practice this means that holes must not be in the preparation area.
  • the preparation area can be located based on manual selection or preferably automatically detected e.g. using feature detection. Examples of critical holes 1000 in the preparation area are shown in Figure 10 .
  • Noise may lead to less accurate scans.
  • Noise is a particular dominant problem when scanning into cavities like impressions, since the cavities creates significant amount of tracking and half occlusion noise.
  • Half occlusion noise is described in details in Curless and Levoy (1995). Lack of accuracy due to noise 1001 is shown in Figure 10 .
  • Half occlusion noise and coverage is the main limitation for practical use of impression scanning and determining whether a scan points is a noise point or a true point is very critical for the final quality of the dental restoration. Hence it is very critical to determine noise and coverage problems automatically.
  • Noise points might be automatically detected using point quality derived from the laser tracking, surface orientation at capture, multiple cameras views, local surface statistics, surface curvature, shape statistics or reverse ray-tracing.
  • an accurate three-dimensional model is meant a model that possess such accuracy that it may be used directly for producing the dental restoration.
  • Another important quality evaluation that instantly can be derived from the scan is the quality of the impression and preparation, respectively.
  • the quality of the impression and preparation can be evaluated based on the scan e.g. by under cut detection, air bubble detection, noise level, impression material evaluation, shape evaluation or geometrical measurements. The result of the evaluation can be shown visually on the 3D scan to guide the dentist to improve the impression or preparation.
  • an impression and preparation quality evaluation might potentially lead to taking a new impression or improving the preparation.
  • a fast scanner such as the 3Shape D250 scanner, is employed so that the evaluation may be performed while the patient is waiting. This could significantly improve restoration quality and/or reduce patient discomfort and cost by eliminating the delay and effort involved in a second consultation to retake an impression.
  • the quality evaluations described might also be performed on other types of scans of the mouth region such as traditional 3D scans of gypsum models, directly in the mouth scans, CT, MR or x-ray scans.
  • Scanning into cavities like a dental impression is a challenging problem using a price competitive structured light scanner.
  • the problem originates from the fundamental construction with a light source projection a pattern onto the object where one or more sensors acquire images of the projected pattern.
  • To perform the 3D reconstruction an angle of typically 20-30 degrees between light source and sensor is required.
  • the required angle and the fact that the sensor and laser need to see the same point on the surface at the same time to make a 3D reconstruction strongly limits the scanners ability to scan cavities.
  • the actual viewpoint becomes crucial.
  • Scanners with at least 3 axis such as the 3Shape D200, D250 or D300 scanner, can reorient the object in 3D and hence change the relative viewpoint.
  • Adaptively changing the view point and scanning sequence to match the individual object can be applied to obtain coverage in difficult dental impressions as described in WO 2006/007855 .
  • the quality of the impression scan is improved by selecting or automatically detecting one or more regions or interest and rescan such regions of interest.
  • the rescanning may be conducted using a scanner and/or scanner setting optimised to the specific region of interest.
  • Missing areas can be rescanned by detecting these in the initial 3D dataset and then calculating the optimal mechanical positioning of the impression or the 3D sensor with regards to their relative position in order to cover the missing areas in an additional automatic scanning session.
  • the optimization function takes into consideration the exact position of the detected hole and also the surrounding impression geometry that might occlude the view of the light source and/or cameras.
  • the rescan could also be performed by utilizing an additional 3D sensor (camera and light source) or one or more extra cameras in the scanner.
  • additional sensor should have a smaller angle between light source and camera and would thus be able to look into cavities with a higher debt to width ratio.
  • a camera and light source combination with a higher angle between light source and camera could be used to make a first scan and then an additional camera or light source with a lower angle with respect to the light source/camera could be used to cover the deepest areas of the cavities.
  • the rescanning may also be conducted after having cut the impression to improve visibility. If the required cuts destroy areas with needed information then the scans before and after cutting can be aligned and combined to form a complete 3D model. Typically the uncut scan will include the margin line area, which will then be cut away to create visibility into the deep cavities corresponding to leaving the impression of the top of the teeth remaining. However, the model may be cut one or more time to achieve accurate scanning. The model is scanned prior to each cut and the corresponding three-dimensional models may then be aligned either sequentially of simultaneously.
  • the problem of scanning into the cavities is solved by making a model of the cavity(ies) by filling a filling material into the cavity. Then the model of the cavite(ies) may be scanned, and the scan(s) aligned and combined with the impression scan.
  • at least two cavities are filled, such as at least three cavities.
  • the cavities may be neighbouring cavities or cavities separated by one or more unfilled cavities.
  • FIG 10a and 10b The process is illustrated in figure 10a and 10b where 2 preparations are lacking coverage 1000 and one preparation has noise issues 1001 create quality problems.
  • the models for 3 problematic preparations are then poured as separate gypsum models 1100 using the impression. These 3 "positive" models are then scanned 1200 without quality issues and the scans are aligned and merged 1103 into the corresponding preparations 1102 in the impression.
  • the alignment might be performed by selecting corresponding points 1104 on the two scans followed by an ICP alignment (Besl and McKay, 1992).
  • the problem of scanning into cavities is solved by combining rescanning of regions of interest and model scanning.
  • it is preferred to provide models in that the models may be prepared manually and for example clearly include lines delining the tooth, so that the scan also includes the distinct lines.
  • the visual properties of the impression material are also very important for the scan quality. This is in particular true for a deep or thin tooth where inter reflections can create image tracking software problems and significant noise. Problems with half occlusion noise at the edge of occlusion can also create significant scanning artefacts, which might be removed by a reverse ray-tracing algorithm.
  • the aligned scan are combined, e.g. by replacing the impression scan parts with corresponding parts of the model scan or region of interest scan or both and merging the common surface of the scans.
  • the alignment of the scans may be conducted as described below in relation to the three-dimensional model including bite information.
  • a step of pre-scanning the impression can be included before the impression scan is conducted.
  • the information obtained from the pre-scan it is possible to adjust the scanner settings and scan sequence incl. motions for making more accurate impression scans or regions of interest scans.
  • the whole impression scan may be used to provide the model, or only a region of the impression scan may be used. Therefore, in one embodiment a region of the impression scan is defined before alignment, and in a further embodiment alignment is conducted only for said defined region. In one example the alignment is performed for at least two teeth, such as at least three teeth.
  • the reflectivity of the impression material should be as little as possible.
  • the impression material is coated before scanning, such as coated with a non-reflective coating thereby improving the scanning quality.
  • the impression itself is made from a material having a little or no reflective characteristics.
  • Alignment of upper jaw scan and lower jaw scan may be conducted by any suitable method.
  • the alignment is conducted using CT-scans or MR-scans of the jaws.
  • One advantage may be that such scans also include information of jaw and nerves.
  • the alignment of upper jaw scan and lower jaw scan is conducted using a double-sided impression scan, for example as described below.
  • CT-scans and MR-scans may be used for other alignment purposes if necessary.
  • CT or MR scans might also be combined and/or aligned with impression scans, e.g. for design of drill guides for implants or simply to provide an improved three-dimensional model.
  • Three-dimensional model including bite information
  • the basis for the scan is at least two dental impressions.
  • One impression is a double sided impression that captures the upper, the lower jaw and the bite in one impression.
  • the double trays may lack physical stability creating lower quality impressions and is not accepted by many dentists.
  • At least one single side impression is also created, thereby mapping only the upper or lower jaw.
  • the single sided impression is created in a traditional tray with very high physical stability providing high quality impression.
  • the possible quality problem with the double sided impressions can be solved by aligning and combining scans of the double sided impressions with one or two single sided impression scans.
  • the accuracy requirement at the prepared teeth area is 20 microns where as the bite and the antagonist teeth only requires 50-100 microns.
  • an additional single sided scan is made of the antagonist side.
  • the next step after scanning is to perform a region-based alignment of the single impression scans 100 with the corresponding double sided scan 200.
  • a region 400 is defined where common high quality exists.
  • the definition of the region can e.g. be performed by an operator or automatically by the computer.
  • the alignment can be performed e.g. using the ICP algorithm (Besl & McKay, 1992). The superimposed result of the alignment is shown in figure 5 .
  • the alignment of the two double side impression scans requires a tray that facilitates scanning of common data such as vertical sides 600 of the tray and special alignment features e.g. a T-shape 601, dots or vertical lines.
  • common data such as vertical sides 600 of the tray and special alignment features e.g. a T-shape 601, dots or vertical lines.
  • the initialisation for the alignment can e.g. be done by the computer or by the user selecting two corresponding points 602.
  • the superimposed result of the alignment is shown in figure 7 .
  • the tray might be designed such that it fits directly into the scanner for easy handling.
  • the tray may include a fixturing system for connecting directly to the scanner.
  • the tray or impression might also include a horizontal eye line to be aligned with the eyes of the patient so that visual appearances of prosthetic tooth/teeth may be aligned with over facial features of the patient during the design.
  • tray may preferably be combined with any of the methods and systems described.
  • the double sided tray can be placed in a scanning fixture, which is included in the two scans. Only the fixture then needs to contain common data and alignment features. The impression may be turned automatically.
  • aligned scans are combined, e.g. by replacing the double sided scan with the corresponding part of the single sided scan and merging the common surface of the two double side scans.
  • a single sided scan can also be performed on the antagonist side and aligned and combined with the existing data in a similar procedure.
  • the double sided tray obtains increased stability by reinforcement, such as a metal, steel, and/or fibre-composite reinforcement.
  • reinforcement such as a metal, steel, and/or fibre-composite reinforcement.
  • such a tray may preferably be combined with the features of the tray described above and any of these trays are preferred when obtaining impressions in relation to any the methods and systems described in this document.
  • the text relating to three-dimensional models including bite information relates to scan of dental impressions, it is clear for the person skilled in the art that the same method and system may be used for scanning a dental model.
  • the single sided scans may be performed by the method for obtaining an accurate three-dimensional model of the dental impression.
  • Another aspect relates to a computer program product including a computer readable medium, said computer readable medium having a computer program stored thereon, said program for producing a three-dimensional model of a dental impression comprising program code for conducting the steps of the method as defined above.
  • a further aspect relates to a system for producing a three-dimensional model, said system including computer readable memory having one or more computer instructions stored thereon, said instructions comprising Instructions for conducting the steps of the method as defined above.
  • Impression scanning becomes particular interesting in combination with CAD design of the full anatomical crowns followed by the manufacturing of the complete crown, both referred to as tooth crown.
  • the full crown might be designed with a suitable manufacturing process such as separating the designed crown into two or more layers where the inside layer corresponds to the coping and the outside layers is the ceramic.
  • the coping can be manufactured using known equipment such as milling, machines, 3D wax printers or sintering machines.
  • the outer layer might be manufactured by first manufacturing a copy in wax, plastic, polymers or other material that can melt e.g. using milling machines or 3D printers. This wax copy is then mounted on the coping and over pressing technologies such as Ivoclars Impress can be used to create the ceramic layer.
  • the dental restoration is implants 1200, which are typically titanium or zirconia "screws" that are inserted into the gingival 1201 and jaw bone.
  • implants 1200 typically titanium or zirconia "screws" that are inserted into the gingival 1201 and jaw bone.
  • the position and orientation of the implant 1200 is transferred from the mouth of the patient to the dental model by the use of impression abutments 1202.
  • the transfer is performed by mounting impression abutments on the implants.
  • a dental impression 1203 is then taken where the impression abutments are fixated in the impression material 1204 and the abutments are released form the implant.
  • the impression 1203 including impression abutments 1202 is removed from the patient mouth.
  • model implants/analogs 1205 are mounted on the impression abutments and the model 1206 is poured from the impression - typically in gypsum.
  • the last step is to remove the impression 1203 and impression abutments 1202 when the model is hardened.
  • the position and orientation of the implant is obtained by scanning the poured positive model wherein scanning abutments are mounted to facilitate easy determination of the position and orientation of the model implants/analogs, and thereby the position and orientation of the implants, from the scanning data.
  • One method of determining said orientation and position from data obtained from the scanning abutment is to overlay the corresponding model data with CAD data of the shape of the scanning abutment.
  • the scanning abutment may be identical to or different from the impression abutment.
  • the position and orientation of the implant is determined directly from the impression by scanning the impression abutment 1202 mounted in the impression 1203 and then use the knowledge of its 3D shape and dimensions e.g. CAD model.
  • the position and orientation might be obtained by features extraction or alignment a CAD of the impression abutment to the corresponding part of the scan.
  • impression abutment is often covered by impression material or hardly surface above the impression.
  • mount a scan analog 1300 on the impression abutment This analog is then scanned as a part of the impression scan and the known shape and dimensions can be applied to derive the corresponding implant position and orientation, e.g. using alignment of the CAD model or feature extraction. This operation can be performed for one or more implants combined or in an iterative procedure.
  • the prior art (6,790,040) describes an alternative method based on encoded healing abutments (EHA) used to determine both the implant type and it's position and orientation from a scan.
  • EHA encoded healing abutments
  • any of the above methods may be improved by including data from in-the mouth scanning.
  • FIG. 1A A traditional sectioned gypsum model is shown in figure 1A .
  • the actually model manufacturing from the scan could be performed using classic manufacturing equipment or more suitable rapid prototype equipment such as milling machines or 3D printers.
  • the model might be manufactured in any proper material such as plastic, polymers, wax, gypsum or ceramics.
  • the manufacturing equipment normally requires a solid 3D/watertight model to be created, see traditional model in Figure 1A .
  • the impression scan 100 only contains a surface and not a solid model.
  • To create an attractive model for the dental lab and dentist one or more of the following virtual steps need to be performed on the scan:
  • the surface orientation need to be inverted.
  • the scan should also be rotated, see figure 15 .
  • the next step will then be to cut away part of the scan surface (material) that is not needed.
  • the cutting can be performed by a splice based cutting tool 1502, triangle selections or other selection/cutting tools.
  • the cut scan surface can be attached or connected to a virtual base.
  • the virtual base can be created by combining the scan surface with a base model e.g. by combing a CAD base with the scan surface by the creation of a connecting surface between the two surfaces.
  • a variant of the process is illustrated in Figure 16 where the cut scan surface 1600 is combined with a base 1601 that is created by vertically extending cut surface into a common surface, in this case a plane.
  • the process is also shown in figure 9a to 9b and 10a to 10b . This may be perceived as forming a new base consisting of the material which is not positioned between two surfaces from the original scan.
  • An important extension to the virtual base is to add an articulator interface 1605 to the solid model such the manufactured models can be inserted and articulated in standard articulators. Optimal results would be obtained by using calibrated articulators. To minimise the manufacturing model cost it might be advantageous to insert a pre-manufactured interface 1606 between the model and the articulator.
  • the step of attaching a base is primarily carried out so that the cut scan surface will be a part of a solid shape which is required for a physical representation such as a manufactured model. Accordingly, one may subsequently cut part or all of the base from the solid shape either virtually or post manufacturing.
  • the trimming of the preparation is traditionally performed to remove the gingival and create accessibility to the margin line area for the crown design. Note for the traditional trimming of the preparation there is no information available that is not present in the impression. Hence the trimming can be performed virtually 1202 even improving the quality due to the controlled environment.
  • the virtual trimming might be performed by selecting the area that is to be trimmed away on the model. One way to perform this selection is by placing a curve such as a spline on the surface part corresponding to the margin line. The trimming might then be performed by removing the surface outside of the margin line and making an artificial surface 1701, 1802 connecting the margin line to the rest of the model 1802 and/or preparation 1701. In many situations it is preferred to also manufacture a tooth crown and/or a prosthetic tooth, bridge or the like from the same model forming the basis for manufacturing the model. In this way booth may be manufactured from the three-dimensional model and the interaction may be physically investigated.
  • the sectioning of the model 1A01 typically into the individual preparations are performed to enable the dental technicians to easily access and work on the crowns, see figure 1 a.
  • An integrated part of the sectioning is the positing system so that the individual sections can be removed from the model and inserted back into the model preserving the original position.
  • the positioning means are pins attached to the sections and accurately fitting into the base. Other examples include screws, bolts, bores including or excluding threads, and push buttons.
  • positioning means are included in any of the sections resulting form the sectioning described below.
  • the virtual sectioning 1603 can replicate the classical sawed sectioning by the use of plane cuts as illustrated in figure 16 .
  • the pins 1700 can then be added and corresponding holes 1604 created using Boolean addition and subtract of CAD models.
  • the virtual approach enables the opportunity to create more advanced and optionally integrated sectioning and positioning means 1800 e.g. using Boolean functions. Due to the flexibility of the CAD design process almost any shape can be applied for sectioning and positioning such as cylindrical, triangles, spheres, cones 1800 or a combination of these 1800. Handles 1801 for easy removal and positioning can also be created e.g. using Boolean functions.
  • FIG. 19 An example of a manufactured model 1900 mounted in a standard articulator 1901 is shown in figure 19 .
  • the model is manufactured using 3D printing.
  • This structure can be the full or partial dental item or interfaces to the dental item.
  • One important example is printing the invention is printing the implant/analog directly as a part of the model, such that the designed structures e.g. customised abutment or super structure can be mounted directly on the model.
  • the implant/analog For difficult implant structures or due to material requirements it might be preferable to use the other option according to the invention, i.e. to add an interface for the implant/analog, such as a slot, so that the implant/analog can be mounted in the manufactured model afterwards.
  • Examples on other dental items are attachments, locking systems other crown/bridge design support structures.
